Mahanagar Gas — Bill charged for excess days

Address:

Harmony(B)/1002, Cosmos Habitat, opposite to High Street mall, near BMC water department,Kapurbawdi,Thane(W)

I started using my connection from 6th October 2021. Today, I received message from mgm regarding Bill payment. When I read the details I got to know that the bill has been charged from 14th September 2021 but I had not even installed the gas pipe at that time. I request you to kindly look into this matter and solve my query as soon as possible
